“Montenegrin” refers to a wide variety of large revolvers chambered for the massive 11.36x36mmR cartridge. They were made by various makers in Austria, Belgium, and Spain. They are found in five- or six-shot configurations. The best known manufacturer is Gasser (see GASSER, LEOPOLD). The type was introduced around 1870. The name comes from the King of Montenegro declaring that all male citizens had the duty to own a Gasser-pattern revolver. Most are double action. The three major types include open-top frame, top-break auto-eject, and solid-frame. Most have a rounded grip frame somewhat like the Mauser Broomhandle pistol. Most do not have a maker or model name. Decorations such as engraving and ivory or bone grips are relatively common, but if nice may add to the value.
